Abstract The corrosion behavior of the foamed SiC/Cu co-continuous composite and the corresponding matrix Cu in 3.5% NaCl aqueous solution was investigated by electrochemical impedance spectroscopy and immersion test. The results showed that the composite was corroded more seriously than the matrix Cu in the solution because of the severe corrosion of Cu in the micropores of the foamed SiC struts which could be mainly attributed to the special structure of the composite and the presence of residual stress.
